Objects dissapear when rendering
For starters, it is only showing up in local view, not global view (notice the lack of layers shown in the 3d view ribbon bar).

The problem is that those object(s) are not applied to any layers.





To fix this, select each object and assign one of the rendered layers to it.





By the way, to switch between global and local view, hit Numpad / or go to View > View Global/Local.
